What kind of cast-on did you use. Backward loop? That might be why there are long spaces between your stitches in the photos. Actually, in the last picture, the stitches on your needles look pretty good. That last loose stitch is the first one you cast on, and with backward loop, it can do that.
Try one of the other cast-ons if you did, indeed, use backward loop.
The last stitch is always loose, though not always that loose. Knit the first few stitches tightly to snug it up.
Your best bet, though is to just keep knitting and not worry about imperfections yet. As you knit, you'll see yourself getting better and better.
