yes, there is no neck in your reference photo. looks like you forgot his chin. his hat should be wider with that proportion. the top one looks the best, so i encourage you to work on that one first. before you continue, maybe you should do some sketches so that you become more familiar with that composition; it may seem rather simple, but when you try to recreate it, it's best that you know every little nook and detail.
Continue to work on the piece, you have a great start!
