Nice work by the way!
 

 Thanks for the feedback. I am not sure how to check the colour count yet but I will keep that in mind. In hindsight I should of started with a smaller canvas.

This is really good, especially that sidewalk and fence.  I also really like the proportions of the people. Really, I don't think there's anything about this that I don't like.  Great job. I look forward to seeing more.

Kind of similar story with me ;) Great begining with an interesting work. But perhaps the picture needs smaller amount of colours. Looking forward for more ;)
