I'm new to art, I started painting and illustrating a couple months ago. To practice I paint the dingiest scenes from the current video game I'm playing: Yakuza Kiwami. I've been painting along to those real time YouTube videos of people doing loose illustrations and watercolors. If anyone has recommendations for learning more about illustrations, watercolor or any other artsy thing please let me know.
Also... If you can read Japanese please just don't. I have old highschool knowledge of the language from 15 years ago, my hiragana is probably mostly recognizable but my Kanji is literally me copying the character to the best of my ability but I don't know what any of them mean. I think I wrote the alphabet around the vending machine...
First off, the marble background, if that's what you were going for, is phenomenal, the color and texture is spot on.
Your colors are begging for more saturation, rich beautiful saturated colors. With some work on perspective and some shadows to support it the realistic vibe I think you're going for would really work well. Unless that's not what you're going for and you've got a vibe and style you want.
I can see some good wet on wet (like the rust suggestion on the pipe, among others) which I love, and given your couple of months introduction is just great to see, wet on wet has a ton of depth to it. Keep experimenting with it. I can see you playing with shadows, they are so hard, but keep trying. Shadows can do so much heavy lifting in a painting when they are done right. 💛
