I have never critiqued on photography before so I thought I just had to do it now. I must say, this is the most cutest guinea pig I have ever seen in my life! He/She is just soo cute! I could just reach out and pinch their cheeks! The innocence that they have is brilliant! Also, the fact that the grass is nice and healthy and the small daisies brings more color to this beautiful guinea pig. You got a great shot especially when they lifted up their head! This expression.. is unbelievably adorable! I would so use this on my desktop!!! The vision and the originality is great and also the technique and impact.
In my opinion, you are a great photographer and I hope others can see that too in you and your work.
