And can you tell us more about honest methods, and what applies to dishonest methods?
Bugbear has explained to us that it is a tracing, which will be accepted in this instance because originality is difficult with this particular PJ challenge.
Thanks for the sharp eye though!
this has striked me as a bit suspicious , so I color reduced the original painting and compared it to your piece as you can see in this gif - (https://i.imgur.com/xsMEjkz.gif).
while I know that its possible to be very accurate to your source with certain methods of art (through honest methods) , in this case it seems to be too accurate for me to believe you made that in an honest method of art , it just seems refined.
To paraphrase some rap lyrics, you "made that [palette] stretch like an 80 inch plasma". Great work, would love to see it run through a CRT filter because I bet it makes the 50% dither very effective (I might send it to Vagrant, he's great at emulating this stuff).
not sure if its a good place to start and talk about it , but I think it should be pretty obvious.
a dishonest method would be to trace , color reduce a picture , pick the colors straight from the picture instead of picking them your self and such methods ..
while an honest method (while working with a source from example) would be to observe it , draw the angles and proportions , and observe the source and try to pick the colors by sight.
those are pretty obvious standards for art in my opinion.
