Hi there mike,
You did a good job bringing out the outer arms. But this is a very challenging object in its outermost portions.
As mentioned in my post in rogerg's recent imaging thread about this galaxy, the disk is not at all normal, and it is quite easy to see in your image that one of the major outer arms actually bends a long way out of the plane of this galaxy!
The arms have an "unevolved appearance" as do those of NGC 1512, as these galaxies have very extended disks which are easiest to pick up in the UV images from GALEX. As we once discussed regarding NGC 1512, one can imagine that these
faint but
optically-evident disks are
still forming from gas falling into the gravity well of a galaxy;
it is virtually certain that the era of disk formation has not yet finished in the universe, for instance some astronomers found that the disk/spiral region of M33 had very gradually formed, starting in the inner part and then working outwards.
Just for fun and profit, here is the UV image of N3621 from GALEX:
An obvious bending or twisting of the arms, out of the primary plane of this galaxy, is more obvious in this UV image.
(and I can prove my case with an image which shows the HI gas disk bending in some weird way)
Best regards,
Robert
This galaxy was recently discussed in the third post of this science thread:

The comparison with NGC 6744 is an interesting one.
but … I’m sure I remember you using a FLI before, now a Starlight Express – have you switched cameras or is this a different scope? Is the SXVF-H694 a new piece of kit you have? 
...eerrrr?..pleeease confirm you knew that wasn't thinly disguised sarcasm meant to offend
