April rewards cover broken (Patreon)

The April rewards are here but also a couple of issues this time:

- I screwed up one of the sketches "Nero from FATE" resolution, while trying to master the new equipment I was adjusting some settings and didn't noticed that I messed up the resolution of said image, then when I exported it, finally noticed... I'll try to fix it (only way to fix it is re-doing it) as soon as I have time, my apologies to patron Thiago Silva who was the one that requested that sketch.

- The monthly cover file got corrupted and as much as I tried to recover it, I couldn't, so again... the only solution for this is... yeah... re-doing it, (if I have enough time, the cover should be redone by tomorrow).

For now I'll post the usual rewards (minus the cover) in a few minutes, thank you for your patience and I hope you enjoy April rewards.
