At this stage, unless you're absolutely certain you can finish both to a high standard I'd focus just on one and put your all into it. It's not worth sacrificing time and quality when only one can be submitted anyway, but I do highly respect your determination and calibre! If you do really want to go with both and finish them, I'll be very impressed xD
I second what @nesokaiyoh said, if you can finish both in time that'll be so impressive! But maybe focus on one
Anyway it looks amazing!!! Keep up the awesome work!
