The quality is much improved if changed to 720p on youtube 
obviously was on 720p and i know YouTube detract from quality but I've seen better 720p stuff from phones.
The problem here is the flat light, consumer grade digital video cameras don't perform that well in low light; looking at Horney's video it looks like it's been recorded on a dull morning which isn't going to have the best light, making the colours slightly washed out an a lack of contrast. This is something that could easily be fixed in post production using your video editing software of choice.
