i had a customer come in and asked for a front view of a train . wants it in color and told me to do my thing with it. im having trouble coming up with something im happy with. ive done 3 different ones so far on paper with over 10 hours invested already and my head is starting to spin. i need a critique on the layout and colors. this is a rough pen and marker drawing so i wasnt trying to make it perfectly clean so dont critique that aspect please.

im pretty sure im either gonna bring the bottom flames in closer as i feel they are kinda overpowering that size or im gonna completely take them out and do something else right there instead. please give me your opinions on this i want knock this design out the park.
