holy smokes! you have been busy ^^ i like that you working on both 3D and 2D! its a bit hard to get a feel overview of your thread tho, maybe its worth a shot to put some of your best finished works in your Top post for easy viewing?
for some 3D sculpting feedback i think you should try to work more with hard edges and clear well worked shapes. try to not use Damien standard brush without shaping and smoothing the surface after for a good and natural transition. try to use more of trim dynamic and H polish, even on Organic Models
keep up the good work ^^ hope to see more 3D from you
