What results can I expect with Damon Braces? Specifically regarding facial aesthetics and teeth. (Photo)

I have a 12mm overjet, severe overcrowding and overbite. Would you recommend Damon braces for my case? I heard of jaw surgery but that is too expensive. Also, would you recommend extractions of 2 upper pre molars to make space? Also, what results would you expect regarding facial aesthetics and teeth? Would extracting teeth ruin my facial profile and how far back do you think my 12mm overjet will go back? I'm just looking for education guesses based on my pics, nothing exact, Thanks.
