Heart- melon

i like the grey wash usage – maybe work on lines – on that particular design i would bold them lines out to hide the shakes – but that’s just my opinion – :D – keep up the good work 8-)

Good incorporation of shadows and highlights. Overall nice work for what it is. Light blue adds a nice effect if used properly to illustrate silver, or chrome. I would suggest not to cover up your mistakes with thick lines, especially when you are practicing on melons. Keep practicing one passing your lines. That is an important skill to master. Obviously it is going to be different in the skin, but developing a steady hand is half the battle.
