Its a good start but I think the head is a little off in its proportions. Have a look at some reference and line it up in a camera or something, as the eyes look a little high and that nose looks huge as already commented. Overall proportions look good but if you are going for a photoreal version then getting it spot on will be key at this stage as its going to get some real scrutiny. The minute you say Photoreal, you gotta be sooooo careful cheers Jay
