@mcschweitzer I love the whole look of this layout! I like that it doesn't feel too polished or perfect. The perspective makes just enough sense that you can get away with little imperfections, and it has definite hand drawn charm. I'm sure it would work perfectly as a children's book illustration ^_^
I recently watched Will Terry's "Draw 50 Things" class, and was surprised to find that he wasn't fussed with super-duper accurate perspective for his interior space. He kept his vanishing points in mind but didn't actually draw them down or use perspective lines as a guide, and he followed the rules just enough to make his image look right. All his lines were drawn purposefully wonky, and the whole finished piece felt natural and visually pleasing. I'm sure that comes with experience and isn't necessarily helpful for a beginner, but it's reassuring to know that once you know the rules you can get away with breaking them a little.
One artist I'm really interested in right now is Izzy Burton. A lot of her pieces are drawn from photo reference, and she uses the lasso tool in Photoshop to purposely make her images wonky in order to add character and charm. I notice she also doesn't draw down her vanishing points or make a grid but goes by eye (she also admits she doesn't fully understand perspective). This is great if you're going for a certain look, so it's good to know that you can be "off" but still get away with it if it's part of your style.
Anyway, I think you've done a great job on this piece. I'd love to see it finished with objects, colour and characters in it
