My orthodontal final look is today & I have a very noticeable gap, could that cause me 6-8 more weeks of treatment time? (photo)

treatment time prescribed = 2 years & that time will be met this August. I had an overbite, slight overjet, & crossbite. what doesnt make sense is that I had rubber bands on 4+ separate occasions along with a spring on my right side that is supposed to be faster than bands & I always wore them in hopes of getting my braces off early, other people did. if today is my final look, will this gap cause more time? or do I just have a small tooth? I was told my bite on my (R) will never be perfect
