I do not mind furry content like some do, however, I must be honest in this critique. This character was referred to as a "gibbon" but I regret to inform you that gibbons do not have tails; they are apes, not monkeys. Overall, the art is competently made but this error is very hurtful to me as someone who likes gibbons (and occasionally wishes to become a gibbon). I recommend erasing the tail if possible. It would be rather easy to do so as the tail does not overlap the character.
For now, I will dry my tears and move on. Thank you for sharing this work. Godbless.
