Thank you! Yes, it's a bit stressful to think you have some credit. My client payed me 100% in advance and I could not deliver it during 3 months. This illustration took me for about 3-4 days to finish but had lots of different things/orders to do instead of this. But I really wanted to draw this cover actually and appreciate my client waited for me. Luckily he told me it's okay and no rush.

But yeah, usually I prefer to work fast and do everything before it will loose actuality :)
