I like it. Although it's not done yet, course. ^^;
* ADD MORE DETAILS. Add wrinkles.... on the bed... and the cholthes.
It looks like he's wereing new cholthes... Add rips and tears and patches to his cholthes to make him more hobo! Make him look like he has taken a shower for days. DIRT! Yellowing teeths.
Look up pictures of hobos on the internet. =/
*Don't forget to shade in the walls as well.... from light to dark
* The colors.... do you want the viewer to view the bed first or the hobo first? Give the hobo warmer colors to bring him out. Or change the bed.... from pink to a cooler color.
*Give the hobo more pinks and flesh tone colors.
