Props for stepping up, something alot of keyboard warriors are afraid to do.,.
some constructive critisicm
A couple things, the first takedown he got on you was weak.. you need to keep your hips back more. You basically gave him the trip
Your a blue belt in bjj? is your normal sidemount escape to try and kick your legs over their head? very unusual..
the only other things that could use some work, he gave you armbar from mount a few times.. when you went for the kimura from side and he bucked you off, you could have sat on his face to finish it topside.. would have been way easier than trying to lock it out from across side.
Nice takedown, and good finish.
