Unique Spaceship Design.

Step 1:

Let’s start out by creating a new file. I used a 600×600 pixels canvas set at 72dpi, and I filled my background with #747B7E color shade. Now in a new layer set and name it ‘Spaceship’. Then select the Polygon Tool and set the sides to 3 with smooth corners checked under the polygon options window.

In a new layer draw a gray polygon with #90979C color shade and 171 x 176 px dimensions.

Step 2:

Under Layer Style(Layer > Layer Style) add an Inner Shadow, Inner Glow and Satin blending options to your gray polygon layer.

Result:

Step 3:

Duplicate your polygon layer design and resize it by 20% and position it as shown below.

Step 4:

In a new layer draw a gray ellipse with #A5AEB3 color shade and 209 x 146 px dimensions.

Step 5:

Under Layer Style(Layer > Layer Style) add a Drop Shadow, Inner Glow, Satin and Gradient Overlay blending options to your gray ellipse layer.

Result:

Step 6:

Duplicate your ‘Spaceship’ layer set and merge it through Layer > Merge Layer Set. Then resize down the duplicate by 50% and rotate through Edit > Transform > Rotate 90 CW. Now place the duplicate layer behind the original ‘Spaceship’ layer set.

Step 7:

Add more small spaceship designs as shown below to complete your unique spaceship.

Step 8:

Add another small spaceship design on top of the original. Then set the layer’s blending mode to Hard Light.

Results:
