Heya, me again!
For the bridge scene, I really like how it turned out. The only real criticism/comment I have is I was wondering what the bright darts of light past the bridge were. They look intriguing, but I'm not sure they really fit. Everything else looks really great.
As for the one above with two people, I think the poses could probably be more dynamic. I really like how the background and shading for it was done, as well as the black-and-white lady's hair. The man's arm muscles are very well defined, but I think his pose looks off/could be more dynamic, as I already mentioned.
Keep up the good work, and I've updated my sketchbook again, so feel free to drop by and add commentary/construtive criticism.
