Here's a weird theme: power tools, but done in a watercolor style. This is the kind of contest that just makes me think they're trying to keep the number of entries down to make voting easier. In any case, instead of focusing on the tools themselves, I did just the chargers. They have such interesting shapes and I wonder what kind of thinking goes into their design.
This was pretty fun to draw. I used some free watercolor textures I found online. However, it only got 12 votes and came in 81st out of 84. Ha, ouch! My favorite was the drill bits.
