I had a series of spot illustrations for a long time 'college prep' publication client in October. There were two different styles that I worked in for these two groups of spots, in order to keep them from looking too similar to each other. The first was more of a cartoon style, like the 'surfing' spot and the 'huddle' spot below.
The rest of the spots were quite a bit smaller in size, and I did these in a simplified 'scratchboard' style. They mostly dealt with 'college' life in one way or another, email, gas prices, lunch, recycling etc etc. A couple of cute ones came out of this batch, I particularly liked how the 'guitar and amp' one turned out.
