There are multiple artists here. It is possible that these were all commissioned BY Fernin, but even comparing 1-10 to the majority of other pictures it's easy to see that different artists are in this gallery.

The artists, as far as I can tell are:

Arania - 1-10.
Cyrus Physhor - 11-44
and sadly the rest of them 'look' familiar, but I don't recall who the artists were.

*for easy proof of different artists, 11-44 all have CyPhy and a date somewhere on them. 45-46 though have a different name.

Base +4, kestrelcoatl +7, DeltaX +8, Lesamuen +9

45-46 - Frux.
47-51 - K. Woods (judging from the signature)

Base +5

Images 1 to 10 were made by Arania
