>>4378863I genuinely think you'd have some better shots if that wide lens didnt go missing. Not to say some of these aren't nice, but I think some anons looked over your OP where you only had your telephoto.
Colours look a bit dull but that can always be fixed with some learned editing and/or OOC adjustments. Might also just be that what you're shooting in frame tends to blend together as nothing really "stands out".
This
>>4378876 is quite decent as the yellow/orange leaves of the background break up the monotone feel to things. The only things I would change about this photo would come down to how wide you can set your aperture to throw the background out futher, and maybe a square crop instead. Both personal preferences.
On that note, I am considering buying the RF 100-400 but also want to save up for an R6; one will happen before the other, but your results are decent enough with the R10.
