Even if there are small anatomical problems, the last one if beautiful! You're really good with grey shading.

Thanks!
Proportions and body structure aren't my forte, but I'm working on improving them ^^

Your art is amazing! I wish I could draw as well as you can. x3 I'm trying to get better at digital drawing, but with little progress. :P I just suggest keep trying. ^-^

Thanks :D
I'm trying to get better at digital pieces too, blending and opacity are still pretty confusing for me >.<
Lets both work hard and become better artist! (^o^)/'

Do you need any help? I've used SAI enough to more or less know my way around it. xD

That would be really kind of you :)
I wanted to know what persistence and blending do when using the marker tool and what tool to use when doing highlights :D

I mostly get my knowledge from browsing DeviantArt al day, soo..

Persistence
When you are going to paint a color over another color on the same layer, it determines how much color is going to go onto the color under it. (I'm actually still a bit confused over this, but I think I'm close. It kinda reminds me of how dilution works...)

Blending
Well, it just basically blends two colors together, heh. :P If you change the slider to a higher number, the more easier and quicker the blending is.

Highlights
Any tool can do it okay, but I think a brush would do it well. Most people also use the 'luminosity' layer setting to make everything shinier. :D

Well, my problem with digital is ALL of it. xD It's hard for me to use a tablet so far. x3 But yeah, let's both work hard. <3
