Think of it as constructive criticism instead of harsh criticism. :wink:
'Yousuck' is correct...most of your drawings have a 'cookiecutter' look to them, so you might try doing as he says. Try varying your poses a bit more...when you do drawings outside of your normal three-quarter front view (like the drawing LV used for the Avatar to your gallery), which for a lot of people is outside their 'comfort zone', some wonderful things emerge. Try some more 'intermediate' inflations, instead of the full-blown stuff...when I do that, it forces me to pay more attention to body construction and anatomic detail. Try some inflation sequences, they can be good learning tools. Do a sequence where you show the inflatees face only...where you can practice with some varying emotional content with the characters facial expression.
That's just some things that helped me come along in my style. Oh yea...try some different drawing styles...like do a drawing using pencil only or scanning and colorizing a rough sketch. Some times rough, unfinished sketches can have a lot of cool things happening in them. Keep looking at what other people are doing and use a keen eye to pick up little detail things here and there.
Above all, don't get frustrated and draw, draw, draw in every spare moment!
Hope you can glean something useful from all that crap! :D
Vary your style a little bit. Draw just some breast inflation or some butt inflation sometimes instead of body inflation all the time.
