Ah- if this is your WIP you should probably remove the 'elf motivation' from the title, words in the title act as tags, so this would class as a second submission, which might disqualify your actual submission.
Anyways, nice work, I like the environment! And I see that pokeball on the shelf there lol, nice touch XD

Woah, you really did do a corkboard :D You were right with your review on my work, it does seem more effective with the posters a little more packed together, and with the main ones being bigger. The three big posters are a clear focal point, so well done on the composition!

I love your clean linework, I'm not all that familiar with digital drawing to be honest, but there's definitely a set style in your piece. And I also love the texture of your cork board, being the only part without lineart, it really allows the posters to pop out. The shading on the gold plaque is also really good, you really captured the shine, and the writing actually does look like it's engraved! Oh, and I know it's only a small thing, but nice touch with the curls of the paper, makes everything look less static and flat.

So well done, again my favourite part of this would probably be the composition, everything fits together so nicely! And good luck in the competition ^_^!

Oh my! And I thought mine was creepy...

I really like this idea, this would definitely motivate me, that hat looks really painful! The drawing is really well done, especially that expression, you can almost see the poor elf descending into madness thanks to his Jolly Top. The yellow nails and teeth make it even creepier, it's like he is so run down from all the work that his health is declining. I also like how you put the number on the hat, it gives some perspective on how many elves are working in those conditions, and it makes me wonder how many poor elves have been fitted into a Jolly Top. Hopefully less, now that they have this poster to motivate them >.<

The only other point I can really make is the colouring, I like that you have used so many bright and positive colours for such a dark poster, it exaggerates the need to be Jolly. One thing to maybe improve on is the shading of your colouring? The shading looks like it's mostly gradients, which do work for a cartoony style, it's just that I feel it makes the poster slightly more flat. I do however like the texture on the wreath, it brings a little more detail, which is personally something I visually like ^_^

Anyways, well done, I love how sinister this poster is, and good luck in the competition!
