No price is too steep for power!!
This is pretty awesome, but I agree with Gawrone, you have a ton of uneeded colors that you could slim down. If you can edit it to lower the count and reupload it then it'll be fine!
Hi. You have used transparency effect in a very uncontrollable way which resulted in your colour count going way beyond necessity. We tend to avoid such things in the gallery, but if you would like to put somme effort in controlling the result (for example uniting the most similar colours, especially those used for singular pixels), I would accept the piece without hesitation.
