The shots are not too bad, but there are a couple of things you probably want to work on.
Both have the bad combination spots of softness (typically the nose and tail areas) and some over-sharpening (DL widget, B6
has halos around the gear and engine nacelles have jaggies starting to show). I'd say the problem leans more towards softness, but be careful how you apply the sharpening.
Both are backlit, but the DL
suffers from this the most. Not much you can do about that.
Both could use a tighter crop, especially the B6
. Lots of empty space around the front of the aircraft.
Both have a really strong color cast in the cyan/blue area, so you'll need to adjust that to the red/yellow side.
All in all, not suitable for submission yet, but possibly after some re-working. The B6
probably stands the best chance in the end.
