Adithya,
What are your thoughts on this series? How do you explain it?
A few years ago I enjoyed doing similar images like
this,
this,
this and
this (and a few others which you may find in my website in older archives). When I was attempting such images along with
aesthetics I was keen on emotional attribution of such creations. While I still love aesthetics part of it my emotional response seem to have got diluted to such creations of mine since another aspect of nature, namely indifferent 'truth' seem to have taken over. While I still love how the birds melt down amidst the forms and shapes of the nature my mind yearn for more - the truth in particular. That said, in field, I tend to comfortably fall back on the previous habits since portraying 'truth' in interesting ways is extremely tough to say the least.
Quick comments on the images based on my aesthetics which you may safely ignore

Image# 1: I like how a few birds become part of the branches. I don't think the vertical out of focus branch on the left adds to my sense of aesthetics.
Image#2: I think smaller bird would have added further?
Image#3: I like it, because I could not spot a bird!!
Image#4: I like how the curves of birds matches with the rest of the forms and shapes.
Image#5: I know where the bird is but I am looking for more...
Image#6: KF is too sharp for my tastebuds and does not see to gel with the rest of the creations
Image#7: Love this, don't mind the centered composition
Image#8: Too sharp?
Image#9 & #10: Seem to work!
Image #11,12,13: Not sure!
Image #15: Works well
Image #16: I like it, forms and shapes seem to naturally merge.
Image#17 (the last color image): Odd man out. Does not seem to go with the rest in the series due to the color.
