Pros:

1-Excellent design and particle effect.

2-Authentic product sticker gives it a little bit more of a feel that it's really zap apple jam.

3-Great design for the label, especially the use of the colorful background behind the actual image of the zap apple.

4-Nice reskin for MLP fans who don't like the nuclear pukey look of the bile. (And for those who would rather something more pleasant in the jar.)

5-Actually went the extra mile to add the particle effect, I've seen some reskins that left the green cloud when the liquid inside was a different color, so I like coming across reskins like these that go all the way.

6-Colors don't just stack as if the jam is really seven different liquids that sit on top of each other like oil on water, I like the shifting effect.

7-Actually makes sense now when the Tank gets a purple glow after being hit by the bile.

8-Potential. Lots of it.

Cons:

Being original here, actually listing cons.

1-The Rainbow Dash seal of approval, I don't know if there's an in-joke here or something, but I'd figure it would conflict with the "Authentic Product" sticker because it would be more likely that Granny Smith would be the one to approve the jam.

2-"Authentic Sweet Apple Acres Product", aside from the Rainbow Dash seal being something that makes me question this, there's another thing that I'd like to mention. Not sure if anything can be done about it, but the way the "jam" sloshes around in the jar makes me feel it's been watered down, which isn't something that the Apples would do.

3-Again, one more thing that I'm not sure if anything can be done about it, but the jar is also something that I feel doesn't really look like it'd be a real "authentic product" from SSA.

4-I think it would've been a bigger plus if the colors of the liquid matched the color pattern of the zap apple. (Red, orange, yellow, green, blue, purple)

Edit: Scratch off #5. I noticed that I was wrong there.

Conclusion:

Pros- 8

Cons- 4

Over all, I would rate this a 10/10 because most of the cons don't take away many points, and the pros make up for the points that were deducted.

Cons:
1- Dash seal (-1)
2- Watered down feel to contents (-0)
3- Jar (-0)
4- Color (-2/4)

Total: 0-3= -3

My reasons for not deducting points for the Jar and Watered down feel is that I'm not sure if it's something that can be helped, and I don't feel it would be fair if it's not.

Pros:
1- Design (+1)
2- Authentic sticker (+2)
3- Label (+2)
4- Skin is more pleasant than puke (+1)
5- Cloud effect (+1)
6- Colors (+2/4)
7- Purple glow making sense (+2)
8- Potential (+2)

Total: 13 + -3 = 10

^-^ One other thing I wanted to bring up was maybe perhaps we could see a jam residue on the floor when the jar explodes in a future update? Anyways, great reskin for the boomer bile, hope I didn't sound too harsh. I really enjoy the skin. I would like to see a version with bloody fingerprints, or maybe blood spattered on it, but it's not important especially when you consider pretty much all the items aren't blood spattered anyways.. (Well, except the melee weapons after being used.)

Edit: Noticed a spelling error along with two errors caused by scratching #5 off the list.
