@Braden-Hallett This is looking so good! not sure if you are looking for feedback or not? I was thinking that the right side of the diving tower should be really lit up by the sun in the same way that the boy is? I think i went a little crazy with my scribble over but i feel like a bit of sun on the side might look right - feel free to ignore of course - as @bnewman said above, it is so helpful to see your process here - thank you for sharing it with us!
@Braden-Hallett There is a bit about this from Giuseppe Castellano near the bottom of this link http://www.gcastellano.com/arttips/theillustratorsportfolio
@Kevin-Longueil I don't think there are mistakes - the things i mentioned could be helping to flatten the image but it really is an Excellent drawing even if it does not have the sense of depth you are wanting - and if you check out my work you’ll see that i am certainly no expert at this 
@TianLian Really nice drawing! - I think the main things for me pulling the background forward hard edges and a tangent. The thinner tree in the center of the two main trees in the left foreground seems to want to belong to the background at the top and the foreground at the bottom - the tree could be curving back but I think it is helping to bring the rest of the trees on the right that are painted the same value and similar edge treatment forward - the bottom of that tree has harder edges and slightly thicker lines which brings it forward and as we near the top the lines fade a bit which help it go into the background - the bottom of that tree creates a tangent on the left too which is a way to bring an object forward that belongs in the background - there is nearly a tangent on its bottom right too. The hard edges on the outlines of the bushes has a flattening effect which also makes them seem to exist in the foreground - another way to bring the background forward is with saturation - your background colors are more saturated than the foreground colors which bring them foreword to our eye - making the foreground much darker will help bring it forward - this looks like it is not digital? could you make a few copies and mess around with value a bit on them? The tree in the foreground should be quite dark in places even if it were a white tree I'm thinking - anyways.. feel free to ignore - I really like your drawing!
@Braden-Hallett I vote for two also - seems like it has much more potential for story
@Braden-Hallett is it possible to just run texture along terminator/halftone area only? They all look very nice to me but I would vote for A if I had to pick one.
@RHirsch I think that it works better for me without the little dog.
@RHirsch Quick cut and paste idea - i was thinking that if you flipped the line and made room for the little girl to be in the bottom right third of the painting it would allow the viewer to circle around the composition by way of the crowd - this would also put her in the midst of the crowd so you could have more reactions if you wanted to - just an idea though
@Judy-Elizabeth-Wilson These are great! (my daughter Loves your coloring book by the way!) Do you think you will make another?
