Here it is I found it

I found the paint over of the value study I posted a while a go

Heres the critique I got
"It's all about contrasts: light against dark, soft against hard, blurry against sharp, low detail against high detail. You need to make sure the whole thing reads as a big, soft, potato-shaped blob before you get into teeth and incised lines and other details. Big shapes first, then smaller shapes."

Another tip I got on this painting
"Paint big shapes with a big brush and small details with smaller brush. Start with big one and add smaller parts afterwards. Also think about edges, make them sharp, don't smudge them."

Another Value study

Here's another Value study on Photoshop. I did this while in a Google hangouts call with a bunch of other art students from around the world. It was quite fun actually and weird at the same time like we all come from different countries but we were brought together by just drawing and also game of thrones and the internet but still pretty cool definitely recommend it.

Also I got some critque recently on concept art.org about this thing which was cool; the best piece of advice I got was to balance my edges in this  painting more to make it interesting, like have some hard edges and contrast it with some soft and lost ones and also have the object interact with the environment its painted in.

I think the person who critiqued this also did a paint over of my work to show what he meant if I can find it I'll post it up one day both for me and anyone who wants to use this tip I got.
