Ok so it actually looks pretty good from a first glance point of view.
The secondary should appear offset at f/4.6 as shown in the image below. Your images seem to be taken off axis from the centre of the focuser a little bit. I suspect the offset is correct. To tell you better we really need a wider view showing the mirror clips or at least the edges of the primary reelection and physical edge of the secondary mirror(put the focuser racked all the way in, not extended and try taking the pictures).
Given you telescope is F/4.6, I would recommend getting some better collimation tools like this or the 2" version (this is a really good set of tools that will allow for very accurate collimation). This will ensure your collimation is bang on (which is important at F/4.6). The other option would be the Glatter laser and Blug (or Tublug). If both of these are out of your budget get a good Cheshire like the Astrosystems Combo Tool (but ignore the instructions as they are terrible). This is also a really good tool that allows you to do all the collimation steps with one tool but it takes a bit to learn.
With the Collimation cap only the collimation process should be (This must be done in order);
1) Centre and round the secondary so it appears in the centre of the focuser drawtube (this only generally needs to be done once and it should be good for a long time). I think yours is OK so I would leave it alone for now.
2) Using the secondary collimation screws either get the mirror clips equally visible or get the periphery of the primary mirror equally visible (you need to have the focuser in a long way to do this).
3) Centre the dot of the collimation cap in the marker using the primary collimation knobs on the bottom of the the telescope.
FYI - Step 2 is hard to get accurate enough for an f/4.6 telescope with a collimation cap, Steps #1 and #3 should be Ok but would be more accurate with better tools.
Again, I don't think the position of your secondary mirror is off and I would leave it alone until you get some better tools.
