I can't imagine it formed into that irregular shape without the MWay distorting it big time.
Also all the blue stars. Is that because it has lots of new hot stars?

Regarding the shape of the SMC,
this article may explain it?

namely:
"
In looking at this data, the team also observed that all the stars within the Wing—that southeast part of the SMC—are moving in a similar direction and speed. This demonstrates the SMC and LMC likely had a collision a few hundred million years ago."
There are several reasons for the prominent blue/teal/cyan in my image..
1) There
are a lot of blue giants and plenty of star birth going on!(Great article
here)
2) I added OIII to the mix which imparts a slight teal-cyan hue
3) I just like the look with the blue/cyan/teal turned up a little
While I have certainly favoured the blue for my own aesthetic preferences, there is no doubt the SMC
is indeed rather blue see:
Gendler and
Gendler et al (multiple scopes, including DSS data) and
Lorenzi
Hope that was helpful Greg
