This is my first post in ages, maybe my first ever post. I'm eager to improve my skills rapidly and spent four hours this afternoon with stylus to tablet PC drawing the splendid jewelry gallery in the V&A Museum, London. It was very crowded but I wanted to focus on the environment. I find this picture eerily empty looking back at it!
I believe I need to learn some basics about painting like this. I used Photoshop and rarely took the brush off 100% opacity, and I only changed layers occasionally. I also moved from one part of the painting to another, working-up the detail of areas in isolation. I don't know how to bring up a perspective guideline grid in Photoshop, but I did spend a bit of time at first trying to find out how to do so in the menus. I haven't calibrated my laptop screen's colour... So much to learn! I'm pleased with my focus and perseverance, tho', and want to do better next time!
