Basing my Lizardmen

 I wanted to have a tropical feel with a rich grass base with pools of water and spikey plants.

I usually base my models by placing them on the wet filler, a plastic based filler needs no glue and is almost instant, a sand based filler needs a little Copydex and left overnight to dry. 

The pools of water are rather simple. 

I left areas with no filler or scrapped it off, painted the flat area white, then some Ice Blue, any light blue will do, then Aethermatic Blue as a patchy finish, looking for a patchy algae bloom. 

Finally PVA glue twice, sometimes a with a 2nd coat of Aethermatic Blue between the PVA layers. I then painted the earth a medium brown as I intended to cover most of it I didn't do my usual Iraqi Sand dry brush.

I couldn't make my mind up if I was going to flock before or after I added the plants, in the end I did both but preferred the before. 

If you flock after doing the plants you may end up flocking the plastic and or leave bare earth under them. In temperate basing I think bare earth works, I didn't want it in my jungle bases I wanted rampant growth, but for the swampy light infantry units I wanted a little earth showing

Doing the plants - for sources look at Using plastic plants, sources and application

My spikes were made using elements from a Topiary ball, 

I used either elements 1 or 2 cutting off one part (3) then cut that in to three parts (4) or sometimes 2 by not cutting at 'a' to give me a taller piece.

I drilled 1mm holes to plant them, especially for the long pieces (at the back right in image).

However, if I wanted to achieve the short stubby spikey bits I had to drill 2mm and even 3mm holes to pull through all the stems so I only had the leaves. (Front and sides in the image.) 

Be very careful when drilling, especially with brittle 3D prints, fortunately the glue back together well.

I'd often start with a small size to lead the way, then use larger bits, testing the piece I wanted to pull through using large bits up to 3mm and usually using pliers to pull them through.

When I had the right size hole I'd use loads of superglue gel locating it amongst the leaves where they'd be squeezed together, look at the last image see all the plastic. Before I started doing this excess glue the elements were falling out.

When it was set, I'd cut off the pulled through excess and push in more super glue.

You'll be picking superglue off your fingers for a while, frequent washing during the process helps. 

Be very careful your gluey finger doesn't touch the painted model. I tended to do this a little at a time wondering if it was worth the effort.
