I'm excited to be starting a bttf corner. Marty is my first prop and have a few smalls on the way. Nike Air Mags and Grays Sports Almanac en route. Hopefully I can jump on the next hoverboard run in the project runs!
It's not a question of posting a sculpt for comparison but a question of opinion. We think this sculpt doesn't have much similarity to Michael J Fox (especially on the mouth IMO) but if you like it and you're comfortable with it go and have fun with "your Marty" :thumbsup
All I'm saying is the only other attempt at Marty I've seen is Howard S studios which is pretty spot on. But its also thousands and thousands of dollars. Sold on ebay for $8,500 to be exact. I have under $1000 on my whole statue so for the money its pretty good to me
