This is my first part. It is actually a sticker.
It comes from the model 8808 - F1 Racer.
All feedback is welcome!

Sorry for voting hold directly on your first part.

Here are some hints that should be used for your the next sticker submisions:

The side faces of your box are BFC invers (Red instead of green faces in BFC check.) You need to reorder the coordinates of these quads.

As a rectangular sticker contains a simply box without any edges or condlines you could simply use a box5-12 prim:
1 16 0 -.25 0 18 0 0 0 .25 0 0 0 21.6 box5-12.dat

Next is the part description:
The dimension of a sticker is limited to one decimal place. In your case it would be rounded to 2.2 x 1.8.
For having it correctly sorted you must add an addition whitespace in front of each dimension if dimension has just one digit -> "Sticker 2.2 x 1.8 ..."
Main Words of the description must start with a capital letter: "Race Logo"

I would suggest: "Sticker 2.2 x 1.8 with Black 28 on Checkered Red Background Race Logo" or something similiar as this is describing the sticker a bit more detailled.

This is a new attempt of submitting a sticker.
My previous attempt got a 'hold' from MMR1988. A message to MMR1988: You apologized, but this is not needed at all. Your feedback is very constructive, so I am really happy with that. Thanks.

I hope it is now OK, but if it isn't: let me know, all feedback is welcome.

welcome on the tracker ..farmer

the horizontally continuous lines (through the 8) or their vertices have partly different heights .... should be at the same height ..

the 8 itself seems very undifferentiated in the symmetry of the curves .... would be something to optimize

I think, Ulrich is right.
I just took the real part to compare against. The diagonal black lines seems a bit to thick and should have all the same thickness in your part.
The digits could get a bit better formed for symmetry reasons.
The black lines around the yellow stripes are a bit smaller at the real part.
If you need some high res scans for the side and front part part just let me know.

Thanks for the feedback! @MMR: I would be happy to receive a high-res picture/scan of the stickers as I used a very blurry one. I sent you a private message on the forum.

I will be out for three weeks, so if there is no update, don't be afraid that I lost motivation :) as I will come back after those three weeks.

Hi Charles,

welcome here. Technically your sticker looks okay to me. If you wanna learn and improve on your skills I suggest using some primitives in LDPC as guidelines for the curves of the 28. Something like:

1 16 8.013 0 12.898 6.47537 0 0 0 1 0 0 0 6.11591 4-4disc.dat
1 16 8.013 0 2.217 7.11658 0 0 0 1 0 0 0 6.83791 4-4disc.dat

as we prefer "ideal" patterns:

(I know I Know we should really document all this tribal knowledge if only we wouldn't prefer authoring parts than writing tutorials.

Your sticker would also benefit from some KEYWORDS:

https://www.ldraw.org/article/340.html#keywords

I guess "0 !KEYWORDS set 8808, formula one racer" would be fine

Hold vote for missing keywords.
Maybe the pattern can be get some smoother curves for 28 if it's touched for adding the keywords by somebody else or the parts author after his 'long' the weeks of vacation ;-)
