I do not live in Colorado, which is obvious because of my zip code. But since I don't live in Colorado I will only comment on the obvious communities of interest problems which are urban and rural areas. The biggest problem is that little arm in district 4 that takes in some of the Denver suburbs. Another issue I have is you could have followed county borders a little better while still keeping communities of interest intact. I do like how you took in some of the Hispanic areas (+ Pueblo) in the southern part of Colorado and brought it in with the 4th. I made a map taking in much of the criticisms I had and kept all that I liked. It is still quite similar to your map. Since I am just a regular person and the census just came out I don't have the perfect population for each district but I did everything I could with Daves Redistricting. I added a geojson file and a png of the map.
