HTOTM: FUSION
I'll give my real .02 because I think you can take it.

Your self portrait is really flat. Just by adding a small amount of shading a preserving some highlights, and you could really bring some depth to that image. Other than that, your proportion is fairly decent, but your neck is super skinny... maybe it's that way in real life ;)

As for the abstract... well, abstract is abstract. However, if you draw to the edge of the page in all areas, it will make the piece feel more complete.

There ya go

Face is to Flat as everyones said before use alot of tone. More darker area's try completely cover the drawing in pencil then pick out highlights with a rubber.

For The Abstract Tbh, I dont like it , it just looks like my english jotter; full of doodles and random shit; Abstract needs a subject to it cant just be anything although many believe it.

So Post some upgrades or other works so i can follow your progress.
