Hey Ejun,
Nice to see that you are playing around, especially with high angles and such, though at such angles means that you would have a hard time getting catchlights. It's like a either/or scenario when you are working with just that one light with no flags/reflectors to throw it back into the eye. So it's whether to get the dramatic, chiselled look from such a high angle, and lose the catch lights, or put it a little lower so it appears, but in the process changing the context and feel of the shot.
Agreed with Myopia's thoughts on the "Before the Shoot" shot with the shadows... The shadow from the outfit added a rather angular shape to the model's shorts, and some people may mind about that half-hidden shadow as it can have an effect in changing the shape of your subject.
However, as an artist, you have the perogrative to decide whether to have it there or not. If you hadn't thought of it yet, perhaps knowing where your shadows go is an additional point to consider when you light your subject... though if you want to knowingly leave things to chance, that's your perogrative too... LoL... May sound rather confusing, but on the bottom line, "the artist's intent" is the important thing here - it affects how and what you want to show to your audiences.
For the shot: "First Change", light at the top works well, and the scratched backdrop looks great, and is full of oomph and texture. Though a problem happens at the lower end where the thigh and knees... where the fall off and low brightness meant that you'd won't have a lot of definition on the thigh. Also, the angle of incidence also meant that the quadraceps were lit but not the hamstrings, and as such, it made the thigh look small in comparison to the knee joint.
A possible way to work around is that if you find that your modifier is not giving you the right amount of control on your subject, change to another modifier and see if it works for you, if not, change the distance maybe (bear in mind the light fall off - technicalities) or, change angle of attack etc...
For the shot: "Second Change", The thighs are lit pretty fine imho, though the portions with subtleties like small regions of shadows and highlights are something to be looked into. There's a bit of a controlled chaos in this shot, and it's actually something I quite like. I would have done my shot similarly, only that I'd use a much harder light. Also, as what Myopia have mentioned, the zip of the dress is seemingly causing some issues which can affect the overall shape - little humps and the larger puffs that appear from a high light angle. So yeah whether or not the outfit is messy or straight is something to be considered about in your creative process (artist's intent)
On the overall, the lighting (from the mola) is rather soft, which is, still very much your style... Since you've mentioned earlier that you might be getting tired of softboxes, and if you really wanna go crazy, suggest you ditch all your soft modifiers for a while and experiment with hard lights and crazy angles - stuff that would make your usual viewers squeal in discomfort, but it might open up new worlds and new perspectives...
Side note though - I would love to get my hands on the mola myself... hehehehe...
Hope the feedback is helpful!
With regards,
