Really like the left one in the first picture! I did quite some sketching and drawing in the past. What you were saying about 90% finishing and losing interest sounds very familiar. Stepping away from it for a while to finish it later really helped me.
Keep on going, you do not become a master over night! :)
Thank you, yeah it did help stepping away for a bit, or quite a while haha ! Thank you, I will keep going !!
