Edit: Ichneumon posted while I was writing this, so some of this advice has already been said.
Well, a few specific critiques...
Anti-aliasing. You have some major issues with pixellated edges to your shapes, and to fix that I reccomend resizing in Irfanview, as described in lankybugger's Paint tutorial
. Making the comic in a different tool to MSPaint would help fix that.
In English, we read from left to right. Thus, speech bubbles that come first should be to the left of speech bubbles that come second. Thus, the turqoise baby's "Better be" should come after the "Soon dear" in panel 2.
Jack's "G-guys..." should come before the response ("Not n
ow Jack"), otherwise the response gets read first.
The text is surrounded by bits of white, presumably an anti-aliasing issue. You should use the fill tool in all the places you need before entering any text, and indeed it is better to insert the text using a different program so you can edit the text.
There is no ground in the last panel.
You might be doing it to show an accent, but if I were you, I'd write 'Mister' rather than 'meestare', since I honestly had no idea what you meant when I first read that.
The line thickness around your characters seems to vary for some odd reason. If you simply draw with the line, box, and circle tools then fill where appropriate this should not happen, so I am not sure why it is. In addition, your lines need to be thicker in many cases - 2pt with antialiasing is the generally accepted norm.
Jack has no arms in panel 2.
The baby could do with changing colour from turquoise - I presume he is meant to be a half-orc or something, and thus should be more green. Remember that you can change the colour you are using in MSPaint by double-clicking on it.
That said, using MSPaint is actually seriously hurting your art. I seriously reccomend downloading a vector program such as Inkscape or Sodipodi (both of which are free and open source, so it won't cost you anything). While initially difficult to learn, the tutorials on this site
will help you get past the initial learning barrier, and your images will improve greatly improve due to the many advantages these programs have over MSPaint. If you'd rather not learn a vector program, the Gnu Image Manipulation Program
is an excellent free graphics program, although its interface is fairly hard to use.
I think you also need to work on your story. Currently, I am not entirely sure what is going on. Presumably, this is the strip in which you introduce characters, but I'm still generally clueless about them after reading it. It is probably best to introduce one group of characters at once. There also wasn't a punchline, and a good joke is essential for the first strip in a comic. In addition to this, it is inadvisable to break the 4th wall, as you did with the 8 panels bit, in the first comic.
If I were you, I would remake this comic entirely, with a new script, new art that doesn't suffer from the problems caused by MS Paint, and a good joke. Make sure your writing is clear and easy to read - check it makes sense with a friend or family member.
I hope I'm not being rude or harsh here, and apologies if I have offended you in any way with this post.
