I think there are a few things you can do to improve things.
First, use a different profile / LUT when processing - the one you are using is giving a magenta cast to the sky, which is the single biggest color problem that I see. Also, try the built-in jpeg files - pretty decent actually, and if you are not really using the features of raw capture then the added processing may be unnecessary. Raw will give you good quality, but maybe start off simple at first, and then go to raw to give your images an edge regarding jpeg compression, HDR, etc.
Second, the images as shown here are tiny - about 1K or so. I can't make a meaningful call on how sharp they are. Either everyone else is looking at the images differently, you are capturing at a low resolution (raw still images should be about 4K horizontal rez), or something else is going on that I don't understand.
Third - the images do seem to have a magenta vignette effect, and this could be what you are seeing. Not uncommon with very wide angle, compact cameras like the Mavic has. Do a flat field test by photographing a blurred white wall or other light colored object held up close to the lens. Use manual focus and blur the image as much as possible. Then see if there is a consistent problem with color changing in the corners. If so, you may need to send your camera in.
