Thats fine with the Jazz its good and ill see what I can do for the other one TY

I can, if you find me a good 2D image / decal of the maple leaf logo for the tail. That means that it is not a picture of an actual plane. The only ones I could find were the actual air canada logos which will not work because they have the dot pattern in them.
Additionally, the "Jazz" part will not look like the references, because the texture / model won't support it. It will have to be smaller and offset further back (towards the engines), but will be in the same general area. Is that okay? The same goes for the CRJ-200 too.

Could you do a Air Canada Jazz skin for this plane TY
