I think I did alright with the edge of the pool. I really went into this with no clue on how to render water. I browsed a few garden magazines at work that had pools in them. The details that stood out were the change in value that happened above and below the water line and the shadows and/or reflections. I tried to capture the essence of that with the pool tiles. I changed value at the water-line and made the tiles more fuzzy-edged below. I also included a reflection of the pool's overhang, since I noticed that in pictures as well.
One of the goals for this drawing was to stick to lighter values overall and to have more of a directed light source. Again, I'm not sure how successful I was - if I pushed the contrast enough to suggest a bright light.
I just had an idea - maybe a simple pair of discarded flip-flops on the left might be the final touch. What do y'all think?
Anyway, it was a very hot day here today and my studio is not climate controlled (the garage). Perhaps this was a bit tedious because I wished I was about to jump in a pool. I guess that's why this song popped into mind.
