Sakari, you know what might give your work a significant boost? I really like the ones you do of women in asian-inspired dress, so go grab a few of
these and take them into photoshop with some of the drawings you've done or maybe even some new ones, and play with masking them onto the pieces of fabric and tweaking the blending modes. I unfortunately can't find the examples I'm thinking of right now (Dynasty Warriors fan art), but I've seen it done with some fantastic results. Give it a shot!
